HENRY VHILEY, OF MANCHESTER, COUNTY OF LANCASTER, ENGLAND.

STREET-SWEEPER.

SPECIFICATION forming part of Letters Patent No. 357,440, dated February 8, 1887. Application filed April 27, 1886. b orial No. 200,370. (No model.) Patented in England December 2'2, 1885, No. 7,170.

To aZZ whom it may concern:

Be it known that I, HENRY lVHILEY, a subject of the Queen of Great Britain, residing at Manchester, in the county of Lancaster, England, have invented certain new and useful Improvements in Street-Sweepers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such aswill enable other skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in street-sweepers.

The object of this invention is to construct a street-sweeper in such manner that the same will be capable of intermittently or continuously collecting as well as sweeping during its progress over the area of ground to be operated upon 5 and it consists, chiefly, of a combination of the mechanical sweepingbrush at present in use with a supplemental sweeper for final collection purposes, an elevator for lifting the refuse into the dust cart or receptacle,and levers and chains constructed and combined, as hereinafter described, and pointed out in the claim, which allow one to be raised while the other is lowered;

In the accompanying drawings, Figure 1 represents a side elevation of a street-sweeping machine embodying my invention,the front end thereof being slightly broken away. Fig. 2 represents a plan view of the same. represents a rear elevation of the same and Fig. 4 represents an enlarged detail elevation of the rear part of the sweeping-machine,showing cogged wheels instead of belt-wheels and friction-wheels.

The sides of the conveyer are broken away in Fig. 4 sufficiently to show two of the buckets in full lines; also the contiguous parts of the chain to which they are attached.

The same letters indicate corresponding parts wherever they occur.

In the aforesaid drawings, a is the body of the refuse cart or receptacle.

b is the revolving brush of an ordinary roadsweeper, and is capable of being raised from or lowered to the ground, so as to be in or out of sweeping action at will. To effect this lifting and lowering I make use of the following devices: The shaft of said brush is attached to the lower ends of bars 0, the upper ends of which are pivoted to lugs or brackets 0, ex-

Fig. 3

tending downward from the bottom of the cartbody a. Chains cl are attached at their lower ends to said-pivoted bars, respectively, near the lower ends of the latter. The upper ends of saidchains are attached to arms on a rockshaft, (1, provided also with two longer arms, d and d, the former having a counterbalanceweight, dflupon it,and the latter, (Z being pivotally connected to one end of a long curved bar,-s. The other end of this bar is pivoted to a hand-lever, f. By drawing this lever backward the bar 8 is caused to rock the arm at and shaft d, so as to draw on the chains d, and thereby lift the bars 0 (turning them on the pivots at their upper ends) and the brush b. The weight (1, by partly counterbalancin'g the said brush,facilitates this operation of lifting. The motion of hand-leverfin the opposite direction of course lowers the brush into position for use again. The usual guard or scraper, Z, of brush b is raised or lowered with it, said guard being attached to arms 0 and to a supplemental arm, 1, which is hung to a small shaft, 2 pivoted in one of the aforesaid brackets c. This shaft 2 bears a pulley which receives an endless belt, z, whereby said brush is driven. This shaft is also provided with a cone-pulley or bevel gear-wheel, 2, which engages with asimilar pulleyor wheel,z mounted on the main axle of the vehicle. This axle turns with the transporting-wheels and communicates motion to said shaft 2 through said gear-wheels z and z". The arm Zis not really necessary. In Fig. 3 it is omitted. The chain or band of brushes 9 runs upon pulleys h h,carried by the frame j, which is pivoted to asupplemental bar, f. A chain of links,t,extends from the outer part of frame j upward to an arm, m, of a rock-shaft, o. This shaft has also an additional arm, 12, from which a long rod, 01, extends to ahand-lever 0. By pulling said hand-lever forward said shaft is rocked so as to raise arm at, links if, and framej. The chute 2', arranged below the bands of brushes 9, is connected to arm at by means of a chain of links, it, so that when the brushes are'raised the chute is raised also. Of course both the chute and the band of brushes are lowered by the reverse motion of hand-lever 0. The arm m is provided at its other end with a handle, to allow the lifting and lowering to be done from the rear end of the wagon, if preferred.

Shaft 12 has a long supplemental arm, q, provided with a weight, g, which partly counterbalances the frame j and brushes 5 so as to facilitate the raising and lowering thereof, as aforesaid. The bar 25 is suspended from the frame of the vehicle. The endless elevatingchain V is provided with buckets 10. By these means the large road-sweeping brush 1), after having swept the refuse to the side or other portion of the road, may be lifted out of action and the side chain or band of brushes may be lowered into action, when the refuse will be drawn into the chute and into the revolving buckets of the elevator,which will, in turning over, deposit their contents into an upper chute, w,which conducts the same into the body or receptacle (1.

The elevator \Vis driven by an endless chain, at, which runs from a chain wheel or pulley, w',turning with the transporting-wheels, to another pulley or chain wheel, 09 on the lower shaft of said elevator. This latter shaft carries also a cogged wheel or friction-wheel, a, which gears with and drives a similar wheel, a, on the inner shaft of the endless chain of brushes Variations in detail-such as the form of the various parts and the method of communicating motion thereto-may he made without departing from the peculiar character of the invention.

The operation is as follows: The ordinary large brush, 1), is caused to rotate,as usual,until the refuse is brought in a line, either at one or both sides or other portion of the road,when the collecting-sweeper may be put into operation and the main sweeper lifted. By extending the outer end of this main sweeper beyond the line of the wheels I may use it for sweeping the gutters. As shown in the drawings it extends very little beyond said line, but this operation of collecting may be left until the' refuse has been gathered to the side or other part of the road or street; or by allowing both the ordinary and supplemental sweepers to be in gear together the two operations may be continuous.

The apparatus is provided with the requisite mechanism for gearing up and driving the various parts, and for taking the same in and out of gear, and also with the necessary chutes or guides for the delivery of the refuse both from the brushes to the elevator, and from the buckets, when necessary, to the receptacle or cart-body.

Having thus described my invention, what I desire to claim and secure by Letters Patent, 1s-

The combination of the brush 1) and its shaft with the bars 0, having their lower ends attached thereto, the guard Z, also attached to bars c,and lifted and lowered with said brush, the brackets 0,to which the upper ends of said bars are pivoted, the rock-shaft d, the arm d attached to said rock shaft, the weight d on this arm, the chains (Z, extending from the lower parts of said bars to arms on said rockshaft, the curved bar s,attached to another arm of said r0ck-shaft,and the lever f, to which the upper end of said curved bar is attached,substantially as set forth.

In testimony whereofI affix my signature in presence of two witnesses.

HENRY VHILEY.
